LUBRICATOR.

EFECIFIOATION forming part of Letters Patent No. 290,685, dated lDecember 25, 1883.

' Application filed June 8,1883. (No model.)

"To all whom it may concern:

Be it known that I, TIMOTHY HOLLAND, of the city of Troy, county of Rensselaer, and State of New York, have invented a new and useful Improvement in Lubricators, of which the following is a specification.

My invention relates to that class of devices used to distribute oil to the working parts of machinery, termed lubricators, and my invention more particularly consists, as will hereinafter be more fully described, in certain improvements upon the well-known lubricator patented to J. Absterdam, November 21, 1854, and in which device oil was arranged to drop from a pendent nozzle in a visible form into a conduit-pipe, which conveyed it to the point of application, the oil so distributed being floated up to the point of discharge to fall in visible drops by the water in the cup beneath the oil, and with the cup connected with the boiler for water supply and pressure.

In the accompanying drawings, forming a part of this specification, there are four figures shown illustrating my invention, and in all of which the same designation of parts by letter-reference is used.

Figurel shows avertical section taken centrally through a lubricator containing my invention and improvement. Fig. 2 illustrates in a cross vertical section, taken on the line 00 m of Fig. 1, one of the pendent nozzles, of which there are two in the device, each being the oppositely-arranged counterpart of the other, with said sectionshowing also the connection of the horizontal extension of the oiloverfiow pipes and the nozzles, illustrating also the position of the valve-stem which regulates the supply of oil to the pendent nozzles. Fig. 3 shows a horizontal section of the parts, taken on the line 0000 of Fig. 1, in an enlarged proportion, to better illustrate the details. Fig. 4 illustrates a modification of the sightopening applied to each of the two opposite sides of the lubricator, through which to see the descending drops of oil, and in which modification there is shown a single pane of glass, used at the front and rear of the lubricator, made large enough to open a view of both pendent nozzles, instead of two sightopenings, at the front and rear, being constructed with one pane opposite each of the two nozzles at the front and rear.

The several parts of the lubricator and those constituting my invention are designated by letter reference and their construction de- 5 5 scribed as follows:

The letter L indicates a chamber for containing oil and water, the position of the oil being designated at O, and the water at W.

Theletters (6 a indicate two pipes, into which the oil is floated by means of the water beneath it in the chamber L.

The letter O designates an upper inclosure, divided in two parts by a partition, P. extending from front to rear, the parts of the upper chamber thus divided off by the said partition being indicated at (Z (Z. The oil-pipes a a are constructed to pass upwardly through this partition, and to each turn out laterally and oppositely, to connect with the pendent 7Q nozzles N N, each of which opens downwardly into one of the chambers (1 cl.

The letter V indicates a plug-valve arranged on each one of the lateral extensions of said oilpipes a a, by means of which the amount of oil floated up into said pipes to be discharged from said nozzles may be regulated.

The letter S designates a steam-pipe connected with the boiler, and intermediately provided with a valve, V, to regulate the amount of pressure entering the lubricator through the pipe S. This steam-pipe opens into the annular cored-out space an, and the latter communicates with the chambers d d, to communicate pressure thereto. The letter S indicates another steam-pipe, which, at its upper end, is placed within the steam-pipe S, being smaller than the latter, and with its upper end opening into said pipe S. The pipe S extends downwardly through the partition I, as shown at Figs. 1 and 3, to near the bottom of the chamber L. This steam-pipe S conveys steam and the water produced by its condensation into the said chamber L. Thus combined and arranged, the chambers d d and 5 L are under the same pressure, and the water which collects in the chamber L serves to float the oil contained therein, so as to raise it up into and through the lateral extensions of the pipes a a to the pendent nozzles N N, from :00

which it falls into the chambers (Z d, from whence it passes by means of the openings E to conduit-pipes, tobe conveyed to the point of application.

At A A, Fig. 1, there are indicated two glass panes, and at Fig. 3 the two panes placed oppositely and at the back of the lubricator are shown. These panes of glass constitute openings through which the downward pasro sage of the oil may be seen.

At A, Fig. 4:, there is shown a single pane of glass made large enough to take in a view of both nozzles, and when used in this form it is applied to a corresponding opening made in I 5 the lubrieator at the front, with one of like construction attached oppositely at the back of the device.

The letterF indicates the frame in which the glass is secured for attachment, and this,

frame may be connected to the edge of an opening formed therein by means of screws with packing, or by any other known means that will make a steam-tight joint. The smaller panes A are packed in rings when used in place of the large panes, and the rings are threaded to screw into corresponding openings made in the lubricator, or they may be attached in any known manner by which a steam-tight connection may be produced. The panes used in either way have but one function-that of producing a means by which the descent of the oil may be seen.

The letter 19 indicates a pipe connecting with the chamber 'L at a; V a valve for closing such opening and pipe, and G a cup connecting with the pipe for supplying oil to the lower chamber, L.

The letter D designates a drip-cock for relieving the chamber L of an excess of water.

In the older Absterdam patent alluded to, but one pendent nozzle was used, from which the oil dripped into the open end of a conduit-pipe. In my device'two nozzles are used, each of which opens into a separate chamber, wherein the oil drips, and each of the chambers is provided with a conduit-pipe, to con vey the oil to the point of application, while the pipes that supply the nozzles are each provided with valves to regulate the amount of oil delivered to each nozzle, so that quantitatively each nozzle operates independently of the other; hence my device is not a mere duplication of the Absterdam pendent nozzle. tors, as an offset made from the body thereof, in connection with laterally-extended pipes, the apparatus necessarily takes up a good deal of space, and when applied to locomotives this feature of their construction is objectionable. Thus made, they are liable to be broken, and such construction adds to their cost. When by my improvement the transparent part of the apparatus, and that by which the proper flow of the oil may be determined, is made a part of the body proper W here glass tubes are used in lubricawithout any offset construction on the device, the latter takes up much less room, is less liable to be broken from its compactness, and the cost of its production is much reduced.

Having thus described my invention, what I claim, and desire to secure by Letters Patent, 1s
